The "<C-]>" keybinding to jump to declaration throws an error

[daveyarwood]

This is similar to #35, but the error message looks like potentially a different issue.

When I put my cursor over a symbol and press <C-]> to jump to declaration, I get this error:

error caught while executing async callback:
NvimError(b"Vim:E5108: Error while calling lua chunk for luaeval(): ...vim/bundle/acid.nvim//lua/acid/middlewares/go_to.lua:13: Vim(let):error caught in request handler '/home/dave/.vim/bundle/acid.nvim/rplugin/python3/acid:function:AcidFindFileInPath [[]]':",)

I couldn't reproduce this one either, though I tried with a java method and nothing happened - instead of showing the error.

If you could give me more details on this one, I'll be able to dig further.

Thanks in advance, Henry

Trying it again today after updating, and it's working sometimes (even for jumping to a definition in a dependency library, or in clojure.core! Nice! :+1: )

It seems like it just fails when my cursor is over a Java inter-op form like System/getProperty. When I press <C-]>, I get the error I posted above involving AcidFindFileInPath, and acid completely stops working after that point, and I have to restart Neovim to get it back.

Another thing I noticed: I'm used to jumping to tags via ctags, and the keybindings for that are <C-]> to jump to a definition, then <C-t> to pop the tag stack and return to where you were. I wonder if it would be possible for acid to push the definition spots to the tag stack, so that <C-t> works? (either that or override the <C-t> behavior and maintain its own tag stack?)

[hkupty]

Can I close this one?

[daveyarwood]

Yep -- since #54, acid.nvim isn't binding <C-]> anymore, so the issue is moot :)
